Pneumatic tire.



Unirse sTiiTns PATENT orticadrill/ILES` M. ELDER, f OF INDIANAPLIS, .lNlil AN PNEUMATIG TERE;

full, clear, and exact description of the invention, such as' will enable others skilled in the art to which it appertains to make and use the same.`

My invention relates to improvements in pneumatic tires particularly adapted for use on the wheels of automobiles and bicycles.

- securely in place.

extending Well It has for its object, among others, to provide a simple and cheap armor for protecting the tire and securing it to the wheel, which may beeasily attached to the rim of an ordina'ly wheel l he invention consists in a metal casing uli around the sides of the pneumatic tire, w ich is held. therein. The tread of the tire is covered by a strip of tough pliable material having lateral 'flanges eX tending within the casing, .whereby it is held Said rnetallic casing is secured to the rim ofthe wheel and because of its incasing sideplates prevents the tire from being tom oil. when the vehicle skids. The tough covering forthe tread of the wheel pro tects the tire from unctures.

The invention a so consists in the features ofconstruction and combinations oi parts vention is ful hereinafter described, `and more particularly pointed out in the claims concluding;` this specification.

In the accom anying` drawings, illustrating the preferre embodiment of my inven tion," Figure 1 is a broken sectional view through the 'rim of a Wheel, single-tube tire, and armor therefor. Fig. 2 is a side View thereof.`

While the preferred embodiment of my iny illustrated in the accompanying drawings and its construction and operationv are described in,.this specification, the right-is reserved to make such changes from the construction shown. and described herein as the scope of the claims hereto appended will permit.

In carrying` out m inventionA I provide side pieces of suitab e metal, preferably a kind which will not rust, said side icces having perforatedilanges, whereby t ey are secured to opposite sides of the fcllies or rim of' Specification of Letters Patent. v Application filed March 42li, 1905.

the wheel. CSaid side pieces are preferably curved in cross-@section to contorni to the sur i'ace ol the tire, and they extend well around said tire, just leaving a space between them at the tread of the vtire preferably less than the diameter of the tire. A preferably solid bearingstrip, oll leather, rubber, rawhide, or a combination ol canvas and any or all of' the other materials `or any other suitable inatev rial is arranged over the tread ci the tire and .has flanges extending withinrthe metal side pieces, whereby it .is held. iliwplace. Said `lhungesare preferably thin and tapering 'to' their edges and o'l' sufficient width to give' a goed. bearing Within the edges of the side pieces. l rlhe central portion ci the bearingstrip is v ery thick and projects some distance from the flanged edges ol the side pieces. The side pieces extend between the pneumatic tire and the ordinary -dat metal. tire on the wheel. Two rows or ol" bolts are used, one set passing through the f ell y and securing the side pieces to the wheel and the other row or set connecting the two sille,.p.iecris outside the wheel-rim and clamping said Side Apieces around the tire, whereby it and the bearing strip are held Afirmly in place.

Referring more particularly to the drawn ings, 1 is the folly, 2 the spokes, and 8 Fig. 1, the inetal tire oi the ordinary whcel.` The side pieces 5 are rovided with inner flanges 6 to engagethe si ol? the iellies, 'curved portions 47 exten dingr around the sides oil the) pneumatic tire 8 and outer (langes adapted' to lie close to the sides ol` the thiol: projecting tween the metal tire and the pneumatic tire.

My armor may be used on any form ofsingie or double tube tire. The bearing-strip should be made slightly srnallerin circumfer# ence on its inner surface than the outer surface of thc meuniatic tire, so that when the latter is fully inflated it will make the bearing-strip .fit snugly within the side pieces; so that it will not creep. The. side pieces or casings Vmay bemade of brass, phosphorlbronze, or malleable iron or cast-steel galvanized or plated. with tin7 solthat it will not rust. Said casings may also be made ol sheet-steel stan'iped to the proper shape and enameled 'go portion i() of the bearing-piecc ll. The thin4 inside.
